TALKING-MACHINE.

Be it known that LDAVI'D APSTEIN, a citizen of the United States, and a resident of Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Talkin Machines, of which the following is" a specication.

This invention relates to new and useful improvements in talkin machines such as are used for reproducing and recording,

sound-waves.

It is the object of my invention to produce atalking-machine of improved construction which will include two or more sound-boxes connected with one or more horns, with a view of obtaining better results in recordin and re roducing and whereby clearer an more distinct sounds may be produced further, to provide means whereby these sounds may be better conveyed into or from the machine and likewise to provide adjustments whereby the sounds may bereceived from or deflected in any direction.

With the above objects in View I have devised the device which is shown in detail upon the accompanying two sheets of draw ings forming a part of this specification, upon which similar characters of reference denote like or corresponding parts throughout the several figures, and of which- Figure 1 showsa sectional side elevation of my improved talkin -machine complete, a portion of the horn eing broken away. Fig. 2 is a detail sectional view of the intermediate adjustable extension shown in the preceding figure. Fig. 3 is a detail plan view of a ring shown in the preceding figures and employed for uniting the several sections of the horn together. Fig. 4 is a sectional plan view of the transmitting mechanism, including double sound-boxes and connect tions therefor. Fig. 5 is. a detail outside elevation of the end late for the soundboxes. Fig. 6 is a simi ar detail elevation of the peripheral casing of the sound-box. Fig. 7 is a detail side view of the brid e-plate which ties the two sound-boxes to ether and forms a support for the transcribing pinholder. Fig. 8 shows an ed e and side ele- Specification of Letters Patent. Application filed October 14,1904. Serial Nth 228,488-

shown in Fig. 4. 11 showsa detached e wise may be of the ordinary design, ada ted to rotate horizontally with the pin to fo low over the same'in a vertically-inclined position. i

In the carrying out of my invention I prefer to em loy two sound-boxes, as is clearly shownin ig. 4, each of substantially the same construction and bearing aninclosure or casing formed of an end iece D and a periphery E, in which is secured the usual transmitter F intermediate of annular rubber tubes G. An arm H, having a divided end to connect the diaphragms of the two boxes, communicates the sound to or from the pin I. This in is held in a s ring frictionwsocket of the liolder J, which older in turn is pivotally connected to the bridge K in a way to permit of the slight adjustment of the said holder and its pin with respect to the bridge. The bridge is rigidly connected to the two forthe construction shown in Fig. 9 an illustrating a boxes, holding them at a roper distance apart, and is provided with ugs K, against which the holder rests. By reason of the screws J being located diagonally with respect to ,each other and with respect to the lugs a slight tilting movement may be im-,

parted to the holder by simply tightening or loosening the screws, as occasion may re quire. On the opposite edge of the box is a second bridge K, which serves to hold the IOO ing of the horn with respect to the sound-box. 1 o 5 The outer end of the T-shaped section M of the horn is referably deflected upward and is supported on its under side by a bracket C. Interior of the horn is a supporting-spider P, whichserves to stiffen its structure and like- 1 1o vation, respectively, of the older-plate for supporting the pin. Figs. 9 and 10 show a plan and end view, respectively, of a modied construction of sound-transmitting 55 mechanism which I may use in lieu of that wise to provide a bearing for the blower Q.

.The shaft R of this blower is journaled in this spider, and a belt-pulley S is attached to its lower end and connected by a belt T with a similar pulley U upon the shaft of the record-holder. construction the blower is rotated by the movement of the holder, shaft, and disk in a way to create a suction, so to speak, and to better convey the sounds in both recording and transcribing. I

In the forward end of the horn I provide a series of holes V and a slide W, bearing a button X for its adjustment with respect to the holes in a manner'to open; an d clo se the same. The purpose of this con'structiohis to provide a more uniform distribution of the sounds as taken from the record and to allow the same ora portion of them to be deflected direct, as will be obviously apparent.

Upon the mouth of the horn-section M,I provide an intermediate section a, which is adjustably connected thereto by means of a two-part ring 12, covering the edges of said horn and section in a way to permit said sections to be turned and adjusted thereon, so as to be extended to either side. Upon this intermediate section is also provided an elbow c, which isadjustably connected to an I intermediate section by means of the ring I) in a way to admit of its being turned to any position desired. To this elbow may be secured, by means of clamps d, a mouthpiece e, which obviousl may be of any desired shape or len th,and i addition to its application to the el ow I have also provided connections for similar mouthpieces to the other sections eating movement from the inner end through of the hornas, for instance, at the nipple fin the elbow. and likewise the nipple g of the intermediate section. This construction of sectional horn is adapted to be adjusted, as described, to deflect the sounds from the record uniformly and advantageously to the several corners of a room with improved results.

In Figs. 9 and 10 I have shown a modified form of transmitter to enga e the record, which I have termed a flexib e connection and which may be used in lieu of that shown in Fig. 4. This connection is formed largely of wire and in detail comprises. the flexible arms 72, ivotally su orted upon ins 'i of a bridge 0, secured to l fle ring E. 'Ilhese arms are connected ,by linksj with a loop. k, attached to the lever I. connected to a block m, which in turn ispivoted to the bridge-plate 7c. The free endof lever n serves to engage the record-communithe loop k and flexible connections above e-v scribed to the diaphragms. F, which obviously It will be seen that with this This lever is pivotallyare secured in and form a part of thesoundboxes, as is clearly shown in Fig. 4.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is v 1. In a talking-machine, the combination with a sound-box, of a horn connected therewith, and means in the horn to cause a current-of air to blow through said horn.

2.. In a talking-machine, the combination with a sound-box, of a horn connected therewith, o enings in the sides ofsaid horn, a slide a(l apted to open .and close said openings, and means to cause a current of air to blow through the horn to conduct the sounds.

3. In a. talking-machine, the combination of a transmitting device comprising a double sound-box, 'an arm having divided ends to engage the diaphragm of the two boxes, a tu e connection wit-h each box, a single horn connect-ion with the tubes and meansto cause a current of air to blow through the horn.

4. In a talking-machine, the combination of a transmitting device comprising a double sound-box, an armhavin dividedends to engagethe dia hragm of t e two boxes and i rections, and means to draw the sound waves therethrough.

' I 6. In .a talking-machine, the combination with a double sound-box and connections therefor to engage a record, of a horn, an extension secured to said horn and deflected to one side, a second extension for" said horn adapted to be deflected in --a diiferent direction each being adjust-ably connected to the other and each provided withan opening for the reception of one or more mouthpieces.

7. In a talking-machine, the combination with a sound-box bearing connections to engage a record, of a horn with branches intermediate the open end thereof and the box,

openings in the horn, and a slide adapted to open and close said openings substantially as described. I
